Now I know what I'll get into response to this, I know Arma 3 is Directed to Infantry combat, but I would still like to see this implemented into the game.
The ability to be able to hit enemy armour and the round either penetrated the armour or ricochet off the sloping part of the Armour Bit like World of tanks in that regard but also know the mod for Arma 2 I44 has played around with the ability to this, so I think because Arma 3 has in build physic X it would be a good thing to add, the fact you have to be careful with facing your tanks and the tactic used by either terrain or objects.
Let me know what you think.
